Csharp 具有 AspNetCore.Identity.EntityFrameworkCore 7 扩展 IdentityUser 的 Blazor 服务器

我正在学习Blazor，需要一些帮助.

我的Blazor服务器项目需要扩展的身份用户.

我想访问登录显示.文件中的FirstName属性，如下所示.

我发现的大多数讨论都太陈旧了，或者没有解决我的具体问题.

我的项目用户

using Microsoft.AspNetCore.Identity;

namespace MyProject.Data;

public class 我的项目用户 : IdentityUser
{
    [PersonalData]
    public string? FirstName { get; set; }

    [PersonalData]
    public string? LastName { get; set; }
}

我的项目上下文

using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;

namespace MyProject.Data;

public class 我的项目上下文 : IdentityDbContext<我的项目用户>
{
    public 我的项目上下文(DbContextOptions<我的项目上下文> options)
        : base(options)
    {
    }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        // Customize the ASP.NET Identity model and override the defaults if needed.
        // For example, you can rename the ASP.NET Identity table names and more.
        // Add your customizations after calling base.OnModelCreating(builder);
    }
}

MyProject的Program.cs

using MyProject.Data;
using Microsoft.EntityFrameworkCore;
using Microsoft.AspNetCore.Components.Authorization;
using MyProject.Areas.Identity;

namespace MyProject
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var builder = WebApplication.CreateBuilder(args);
            var connectionString = builder.Configuration.GetConnectionString("我的项目上下文") ?? throw new InvalidOperationException("Connection string '我的项目上下文' not found.");

            builder.Services.AddDbContext<我的项目上下文>(options => options.UseSqlServer(connectionString));

            builder.Services.AddDefaultIdentity<我的项目用户>(options => options.SignIn.RequireConfirmedAccount = true).AddEntityFrameworkStores<我的项目上下文>();

            // Add services to the container.
            builder.Services.AddRazorPages();
            builder.Services.AddServerSideBlazor();

            builder.Services.AddHttpContextAccessor();

            builder.Services.AddScoped<AuthenticationStateProvider, RevalidatingIdentityAuthenticationStateProvider<我的项目用户>>();

            var app = builder.Build();

            // Configure the HTTP request pipeline.
            if (!app.Environment.IsDevelopment())
            {
                app.UseExceptionHandler("/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            app.UseHttpsRedirection();

            app.UseStaticFiles();

            app.UseRouting();
            app.UseAuthorization();

            app.MapBlazorHub();
            app.MapFallbackToPage("/_Host");

            app.Run();
        }
    }
}

一切都很顺利，数据库也更新了等等.

I simply want to access the 我的项目用户's FirstName property here:

登录显示.

<CascadingAuthenticationState>
    <AuthorizeView>
        <Authorized>
            <a href="Identity/Account/Manage">Hello, -->@context.User.Identity?.Name!</a>
            <form method="post" action="Identity/Account/Logout">
                <button type="submit" class="nav-link btn btn-link">Log out</button>
            </form>
        </Authorized>
        <NotAuthorized>
            <a href="Identity/Account/Register">Register</a>
            <a href="Identity/Account/Login">Log in</a>
        </NotAuthorized>
    </AuthorizeView>
</CascadingAuthenticationState>

LoginDisplay在MainLayout.razor中使用

@using Microsoft.AspNetCore.Identity;
@using MyProject.Data;

@inherits LayoutComponentBase

@inject UserManager<我的项目用户> UserManager;
@inject AuthenticationStateProvider GetAuthenticationStateAsync

<PageTitle>MyProject</PageTitle>

<div class="page">
    <div class="sidebar">
        <NavMenu />
    </div>

    <main>      
        <div class="top-row px-4">
            <LoginDisplay />
            <a href="https://docs.microsoft.com/aspnet/" target="_blank">About</a>
        </div>

        <article class="content px-4">
            @Body
        </article>
    </main>
</div>

如有任何帮助，我们不胜感激.
